"Nine Hundred and Ninety Roses"

Lyrics:

The past is like the wind, but the infatuation is hard to understand

Let’s send each other off over wine If you don’t leave, your figure will be misty

The candlelight projection can’t reflect your face

I still see you alone in the photo

The night wind has become cold and the past is like a dream

My heart feels frozen, how can we not meet each other

It’s hard to let go of your heartache and hard to let go of love like the wind

It’s hard to let go of your indulgence in my heart

I have already planted nine hundred and ninety-nine roses for you

From the day we broke up, nine hundred and ninety-nine roses

When the flowers wither, people are already haggard, thousands of alliances have been made, and thousands of vows have been made Annihilated as the flowers bloom
